Here is your answer:

6.78 rounded to the nearest tenth = 7.00 because the 7 in 6.78 is greater then five.

8.21 rounded to the nearest tenth= 8.00 because the 2 in 8.21 is NOT greater than five.

Convert the rate 30 cm/s to m/h

MrRissso [65]

$1m=100cm\to1cm=\dfrac{1}{100}m\\\\1h=3600s\to1s=\dfrac{1}{3600}h\\\\\\30\dfrac{cm}{s}=30\cdot\dfrac{\frac{1}{100}}{\frac{1}{3600}}\ \dfrac{m}{h}=30\cdot\dfrac{1}{100}\cdot3600\ \dfrac{m}{h}=30\cdot36\ \dfrac{m}{h}=\boxed{1,080\ \frac{m}{h}}\\\\\\Answer:\boxed{30\frac{cm}{s}=1,80\frac{m}{h}}$

Answer: Time spent on Question C=3 9/10

Step-by-step explanation:

Total Time to do the entire quiz= 20 minutes

Time spent on Question A=10 7 /10 minutes

Time spent on Question B=5 2/ 5 minutes

Time spent on Question C=Total Time to do the entire quiz-(Time spent on Question A+Time spent on Question B)

20mins- (10 7 /10 +5 2/ 5)

20mins - ( 15 7+4 /10)

20mins - ( 15 11/10=16 1/10))

20mins -16 1/10

19 10/10 -16 1/10

Therefore Time spent on Question C= 3 9/10
